Intrinsic PEEP and its Determination

Abstract

Facing a patient who presents with respiratory functional impairment, the physician is left with the task of conducting tests to determine whether there is a mechanical component to the illness. One abnormality that must be considered is intrinsic positive end-expiratory pressure (PEEPi). PEEPi [1,2] is the difference between alveolar pressure and the pressure at the airway opening at the end of expiration. It has also been termed auto-PEEP [3], occult PEEP [3], inadvertent PEEP [4], endogenous PEEP, and internal PEEP. Although not difficult to accomplish, precise determination of PEEPi and subsequent interpretation of the results demand a thorough awareness of the pertinent theoretical and methodological concepts [5,6].
